The links 11 end 12 eerve also to hold eeid. jewe in substantially transverse ailigninent so that they will. be maintained in position at all times to si1nnlteneonely engage the tubing.

desired to suspend the tubing from the spider the slip may be seated in the spider wlth its aws closed around the tubing and said jaws will wedge between the tubing and the spider seat and grip and hold the tub ing suspended inthe here.

What I claim is 1. A tubing slip con'iprising a plurality of jaws the facing sides of adjacent jaws having slots, links connecting said jaws whose ends fit into the corresponding slots a bail whose ends are connected to opposing links between the corresponding jaws and pintlcs carried by the jaws and working in bearings in the corresponding ends of said links.

2. A tubing slip including a. plurality of arcuate wedge shaped jaws, links connecting said jaws together, the jaws at one side of the slip being disconnected from each other to permit the slip to'be disposed around, or removed from a tubing in a well bore, a pair of eyebolts connected to two of said links and a bail having overturned ends which have bearings in the eyes of said bolts.

3. The combination with a spider having a downwardly tapering seat, oi a slip tapered to conform to the contour of and adapted to fit'in said seat, said slip including a plurality of jaws whose facing sides have slots form- 1 ing bearings, links connecting said jaws together and whose ends work in said bearings and a means through which said slip may be handled as a unit said means comprising a bail, and means connected to opposing links and located between the corresponding jaws and to which the respective ends of the bail are connected.

4. A tubing slip comprising a plurality of. jaws hinged together, a handle formed with a grip member and side arms, said arms being flexibly connected at one of their ends to said grip member and at their other ends to the slip.

5. A tubing slip comprising a plurality of jaws hinged together, means for handling the slip as a unit, said means comprising a handle formed of side arms and a grip meniher, said arms being pivotally connected to the slit at one 01 their ends and liexihly connected at their other ends to said grip memher.

6. A tubing slip comprising a plurality of jaws, links connecting the :uljaccnt; jaws together except at one open side ot' the slip, eye bolts connected to opposing links, means tor handling the slip as a unit, said means comprising a handle having side arms and a grip. said arms being overturned at one ot their ends and titted through the eyes oi" said eye bolts and being overturned at their other ends and titted loosely into the respective ends of said grip and means preventing the detachment of said arms from said grip.

7. A tubing slip having a smooth upper surface and including a plurality oi" jaws. connecting links intermediate said jaws and having a pivotal connection with the corresponding jaws and connecting the jaws together except at one open side ol the slip the facing sides of the connected jaws having opposing slots iorming hearings in which the respective ends of the corresponding links work, a bail an means conncctimg the respective ends of said bail to opposing links.

8. A tubing slip including a plurality ot' jaws, connecting links intermediate said jaws except at one open side (it the slip, the facing sides oi? the jaws connected by said links and having opposing slots which extend to the outer surfaces oi said jaws and which term bearings tor the respective ends of the correspomling links, pins extendingthrough said. jaws and through the ends ot' the links and tol'lnilig means for connecting the links to the respective jaws, a bail and means connected to the respective ends of the bail and also to opposing links and connecting said bail to said links, said connecting means working between the corresponding jaws.

In testimony whereof: I have signed my name to this specification.
